Aluminum phosphide 56% TAB |Fumigant don sarrafa kwari a cikin sito
Gabatarwa
Aluminum phosphide yana da matukar tasiri wajen kashe kwari saboda fitar da iskar gas mai guba da ake kira phosphine (PH3) idan ya hadu da danshi, musamman tururin ruwa ko zafi a muhalli.
Yanayin aikin iskar phosphine shine da farko ta ikonsa na rushe tsarin numfashi na salula a cikin kwari, wanda ke haifar da mutuwarsu.
Yanayin aiki
Anan ga ƙarin cikakkun bayanai na yadda aluminum phosphide ke aiki:
- Sakin Gas na Phosphine:
- Aluminum phosphide yawanci ana samun su ta nau'in pellets ko allunan.
- Lokacin da aka fallasa zuwa danshi, kamar yanayin yanayi ko danshi a cikin mahallin da aka yi niyya, aluminum phosphide yana amsawa don sakin iskar phosphine (PH3).
- Halin yana faruwa kamar haka: Aluminum phosphide (AlP) + 3H2O → Al (OH) 3 + PH3.
- Yanayin Aiki:
- Gas phosphine (PH3) yana da guba sosai ga kwari, gami da kwari, rodents, da sauran kwari da aka adana.
- Lokacin da kwari suka haɗu da iskar phosphine, suna shanye shi ta hanyar tsarin numfashi.
- Gas phosphine yana tsoma baki tare da tsarin numfashi na salula a cikin kwari ta hanyar hana ayyukan enzymes da ke da alhakin samar da makamashi (musamman, yana rushe sarkar jigilar mitochondrial electron).
- A sakamakon haka, kwari ba su iya samar da adenosine triphosphate (ATP), wanda ke da mahimmanci ga makamashin salula, yana haifar da rashin aiki na rayuwa da kuma mutuwa.
- Ayyukan Bakan Bakan:
- Gas na phosphine yana da nau'ikan ayyuka masu yawa, ma'ana yana iya sarrafa kwari iri-iri, gami da kwari, nematodes, rodents, da sauran kwari da aka samu a cikin hatsi, kayayyaki, da sifofi da aka adana.
- Yana da tasiri a kan matakai daban-daban na kwari, ciki har da ƙwai, tsutsa, pupae, da manya.
- Gas na phosphine yana da ikon kutsawa ta kayan bututun ruwa, ya isa wuraren ɓoye ko da wuya a isa inda kwari ke iya kasancewa.
- Abubuwan Muhalli:
- Sakin iskar phosphine daga aluminum phosphide yana tasiri da abubuwan muhalli kamar zafin jiki, abun ciki na danshi, da matakan pH.
- Mafi girman yanayin zafi da matakan danshi suna hanzarta sakin iskar phosphine, yana haɓaka tasirin sa wajen sarrafa kwari.
- Duk da haka, yawan danshi kuma yana iya rage tasirin iskar phosphine, saboda yana iya amsawa da wuri kuma ya zama mara amfani.
